Chris Colfer was less than impressed when his co-stars sang out of tune over the weekend.
The Glee actor is currently promoting Struck by Lightning, the movie he wrote and stars in, at the Tribeca Film Festival.
Producers on the film were eager to surprise their cast mate Robbie Amell with a rendition of Happy Birthday to mark his special day. As the cast and crew burst into song, Chris was quick to give them tips on delivering a tuneful performance.
According to New York Post, the star shouted out, "Find your key-yyyy," midway through the song.
"The room erupted in laughter," a source told the publication.
Meanwhile, a pair who have no problem finding the right key sang to Britain's Queen Elizabeth II to wish her a Happy Birthday over the weekend.
Composer Andrew Lloyd Webber was accompanied by Take That star Gary Barlow as they gave a rousing rendition of the tune to mark the queen's 86th birthday on Saturday.
Andrew played the piano at his country manor while Gary sang.
The group had all been watching the horse racing at Newbury, England, before they returned to the musical legend's lavish home.
"Andrew thought it would be nice to go back to their house for some refreshments," a source told British newspaper The Sun. "Gary came along as well and Andrew suggested they sing Happy Birthday to Her Majesty. It really was a very jolly affair."
Gary and Andrew are writing the official song to mark the queen's Diamond Jubilee this year, while Gary is also organising the concert to celebrate the monarch's 60 years on the throne.
